Gisele Marie, a Muslim woman and professional heavy metal musician, plays her Gibson Flying V electric guitar during a rehearsal at a studio in Sao Paulo January 27, 2015. Based in Sao Paulo, Marie, 42, is the granddaughter of German Catholics, and converted to Islam several months after her father passed away in 2009. Marie, who wears the Burka, has been fronting her brothers’ heavy metal band “Spectrus” since 2012. “People do not expect to see a Muslim woman who uses a Burqa, practices the religion properly and is a professional guitarist who plays in a Heavy Metal band, so many people are shocked by it. But other people are curious and find it interesting, and others think that it is cool, but definitely, many people are shocked,” said Marie. Picture taken January 27, 2015.
